11 Claims. (01.'158-115) This invention relates to lighting devices forgas burners, particularly to lighting devices of the type comprising ahood having openings in j line with the respective burners ,with a tubeor 5,. conduit means leading from each opening toward the respectiveburner.

When a lighting device of this sort is applied to a gas range the tubesor conduit means leading from the hood frequently are positioned, inuse,

lo' over the burner, or over a. torch head, or foot extension on theburner.

It is well known that in the use of gas ranges the burners should beadapted to be cleaned and removed.

l The present invention contemplates an improvement for permittingremoval of the part of the conduit or tube means which is positioned inuse over the burner or over the torch head, foot extension or otherburner part from position 20 thereover to permit cleaning and removal ofthe burner.

The present invention may be used or modified for use with any existingtype of lighting device such as the flash type of lighting device, orthe gravity type of lighting device, and the present invention may beemployed for removing the tube or conduit means extending to the burnerfrom position over the burner or from position over a torch head, footextension or other 30v means on the burner. So far as the presentinvention is concerned the lighting device may be adapted for use withgases having relatively high or any other B. t. u. Values, and the gasburners may be provided with non-quenching pilot means` 35 or they maybe without such means as, for example, in the type of lighterillustraied and described in United States Letters Patent No. 1,747,015,issued February 11, 1930.

The invention is illustrated in the accompany- 40 ing drawings, inwhich: y

Figure 1 is a fragmentary plan view of an ar- .rangement embodying thepresent invention;

Figure 2 is a fragmentary partial section taken substantially on theline 2-2 of Figure 1;

Figure 3 is a view similar to Figure 2 showing the invention inconnection with a gravity type of lighter; l

Figure 4 is a fragmentary plan view of another 50vembodiment oftheinvention; p A

" Figure 5 is a fragmentary partial section taken on the line 5-5 ofFigure 4 with the burner and tubes in elevation; and

Figure 6 is an exploded perspective view show- 65 ing the hinge mountingfor the tubes directed toward the respective burners in the device ofFigure 5.

'Briefly stated, the present invention mounts the tube or conduitdirected toward the burner so that it may be raised relative to thetorch head 5 to permit cleaning and removal of the burner. Specificallythis invention hingedly mounts this tube so that the part of the tubewhich overlies the burner may' be swung away from position thereover.The terms burner part and part 10 of the burner as used in the appendedclaims refer and are intended to cover the burner itself or anypart onthe burner which .the tube directed toward the burner overlies and fromposition over which the tube is removed to permit cleaning and removalof the burner. This burner part or part of the burner may be the burneras above stated, or a part of the burner, or it may be a torch head,foot extension or other means on the burner and the term is used broadlyin that sense.

In Figures 1 and 2 of the accompanying drawings the present invention isillustrated in connection .with the type of igniter arrangement i1-lustrated and described in the coperiding application of Oscar J. Leins,Serial No. 448,603iiled April 30, 1930. The usual gas manifold isillustrated at 5 and one of the gas burners is illustrated at B. Theburner 6 is fed from the manifold 5 by feed pipe 'l to which air isadmitted at 30 8 in the usual manner. Gaseous fuel is fed into the pipe1 from the manifold 5 by the nozzle pipe 9 in .which the usual gas cockI0 is provided.

The ignitercomprises a tube Il leading from the manifold 5andterminating in a torch head 35 I2 in appropriate proximity to theburner 6. One burner 6 is shown, but it is to be understood that gasranges commonly embody a number of burners, usually four, and that thetorch head I2 may be disposed centrally between such or any 40 othergroup of burners. A protecting hood I3 is mounted over the torch head I2upon a flanged perforated collar I4 below the torch head I2, as

, 'shown in Figure 2. The hood I3 has a ilue I5.A

opening at thedtop, and four openings I6, I6 in 45 the circular sidewall, each in line with the respective burner on the range. A tube I1leads from each opening I6 toward the respective burner, and each ofthese tubes I1 is longitudinally slotted at the bottom thereof, asindicated at I8, to provide for the entry of air.

The torch head I2-has-pilot ilame openings I9 directed radially in linewith the centers of the openings I6, respectively, there being fourpilot ame openings I9 for a four burner arrangement 55 in theillustrated embodiment. At the end of the tube II near the manifold 5 aflash valve 20 is provided. This valve is of the type well known, whichhas a constant by-pass and which, when the button 2l is depressed,effects the ow of greatly increased quantity of gas. A pilot light ismaintained at the ports I3 by the gas by-passed through the valve 20,and when the burner is to be ignited, its gas cock III is opened and thebutton 2I is depressed to admit the flow of the greatly increasedquantity of gas to the lighter, this increased flow causing the pilotllames at the ports I9 to be projected radially outwardly, through thetubes I1, far enough to ignite the particular burner to which gas hasbeen admitted.

Extending from the burner 6 toward the respective adjacent tube II is a,small tube 23 which carries at its outer end the torch head 24 extendingupwardly into the respective tube I1, as illustrated.' rI'he torch head24 has a port 25 drilled in the side thereof and directed toward theburner 6. When the pilot ilame from the ports 'I3 is projected by thedepression of the button 2I, the gas issuing from the port 25 at` theopening of the gas cock I is ignited and remains ignited so long as thegas cock I0 is open. Near the top the flue I has openings 28 and thecollar I4 has openings 29 and is clamped upon the upturned end of thetube II at 30.

In the event that liquid, boiling over the sides of a vessel disposedover the burner 6, falls upon the burner. it quenches the name therefromby closing the burner openings 6', and this closing of the burneropenings 6' increases the pressure within the burner. This increase inpressure causes the projection of the ame from the port 25, over theburner, as indicated in Figure 2, and as soon as the iilledpburneropenings 6 become clearedby the evaporation of the liquid, the gasissuing therefrom is ignited by this temporarily projected ilame. Assuch reignition takes place, the gas pressure within the burner isgradually restored and, accordingly, the ame at 25 gradually recedes toits normal length. i It is to be noted that the torch head'24 extends.upwardly into the respective tube I'I and that, in use, the upper wallof the tube I'I overlies the torch head 24 and protects the same againstquenching. Each tube I'I comprises a relatively short tube I'Iasupported on the hood I3 and opening through the respective opening I6in the side of the-hood. The top of the inner end of the tube I'laextends inwardly into the hood beyond the bottom of the inner end of thetube and is secured at 32 to the flue I5. The outer end of the tube I'Iamay pass through the respective opening IB and may be providedexternally of the hood with a down-turned lip 33. The outer tube IIbwhich, with the inner tube I'Ia, makes up each complete tube or conduitI1, is hinged in this particular embodiment to the hood I3 at 34 and isadapted to be swung into and out of alignment with the relatively shorttube Ila. The hinge mounting 34 for the tube I'Ib may be of any suitableor preferred construction, and the hinged end of the tube IIb maytelescope over the adjacent end of the tube Ila when the tube I1b is inalignment with the tube Ila as shown in full lines in Figure 2.

In the event that it is desired to remove the burner 6, or in the eventthat cleaning of, removal or access to the torch head or 'burner part 24is desired, the overlying part of the tube I1 is removed from positionover the torch head or burner part by swinging the tube Ilb upwardlyabout the hinge mounting 34 as, for example, to the position shown indotted line in Figure 2 in which position cleaning and removal of theburner is permitted. Detent or latch means may be provided for holdingthe tube Ilb or the respectiv'e tubes IIb in raised position, or theymay be held in this position manually or otherwise as desired.

It is to be understood that the torch head and lighter arrangement ofFigures 1 and 2 may be of the gravity" type such as illustrated anddescribed in the copending application of Oscar J. Leins, Serial No.471,180, nled July 28, 1930, by providing the torch head 24 with-asecond port diametrically opposite the port 25 and directed toward thepilot dame at the ports I3. In that case the flashing provision at thevalve or coupling may be omitted and this valve may be a coupling formaintaining a constant pilot at the ports I3. When a burner 6 is to beignited, the cock I0 associated with that burner is opened and gasenters the burner and is ready to be ignited at the burner openings 6'.Gas'also passes through the tube 23 to the torch head issuing therefromin both directions, one stream of gas from the port toward and over theburner 6 and the other stream of gas through the diametrically oppositeport above referred to toward and `to vthe pilot iiame at I9. The gaswhich ows toward the pilot iiame at I9 is ignited by the pilot ilame andthe ameis conveyed back to the torch head 24, thus causing a ame to beprojected over the burner 6 to ignite the gas issuing from the burneropenings 6'. 35

In Fig. 3 the present invention is illustrated in connection with thegravity lighter illustrated and described in United States LettersPatent No. 1,747,015, issued February 11, 1930. In this case the outerend of the lighter tube I'I' which extends from. the hood I3'mountedover and protecting the torch head I2 on the upturned outer end of thelighter tube II', is provided at its outer end with a downwardly openingmouth 38 which overlies thevburner' to receive-gas from the burneropenings when the cock associated with the burner is opened and toconvey the ilame from the torch head I2' to the burner. In this casewhen the burner 33 is to be ignited, the cock associated with thatbin'ner is opened and gas enters the burner ready to be ignited at theburner openings. 'I'he gas upon entering the burner passes up throughthe burner openings and those burner openings over which the mouth 38 ofthe tube I'I' is positioned cause gas to ow up through the mouth 38 andinto the tube I1. 'Ihis gas entering the tube II' by opening the burnerflows through the tube I1 to the pilot ame at the ports I9' of the torchhead I2' where this gas is ignited by the pilot eo ame at the ports I0and the flame is conveyed back to the burner 39 to ignite the gasissuing from the burner openings. As in the preceding embodiment, eachtube II comprises an'outer tube hingedV at 34' and adapted to be swunginto 65 the foot extension 4 I, the hollow interior of which 75 fextension 4i is in open communication with the interior of the burnerI2. The upper end of the torch head 4I has diametrically opposite ports44 and 45, one directed toward the pilot dame at the ports 45 of thetorch head 41 on the lighter tube 45, and the other directed toward theburner openings 49.

In this case the lighter tube which extends from the hood l mounted overand protecting the torch head l1 toward the respective burner l2 isdesignated in its entirety at I. 'Ihe tube 5I comprises an innerrelatively short tube section 5Ia and an outer supplementary tubesection 5I!)l hinged at 52 to the outer end of the tube section 5|a andadapted to be swung into and out of alignment with the inner tubesection 5ia for the purposes previously explained. The relatively shorttube section Bia has xed support on the hood 50 extending through theopenings 53 in the hood, which opening is directed toward the respectiveburner. `The top of the inner end of the tube 5la extends inwardly intothe hood beyond the bottom of the inner end of the tube and is securedat 5l tov the flue' member 55. The longitudinal air slot in the bottomof the tube 5I is indicated at 55 and in use the outer end of the tubeis positioned overthe foot extension 4| with the torch head l0 extendingup through an opening in the bottom of the tube and into the interior ofthe tube below thetop wall thereof. y

The hinge mounting 52 in the embodiment of Figures 4 `and 5 isillustrated in Figure and comprises a pair of ears 58 struck up from thetop of the outer end of the tube 5Ia and apertured at 59. A bracket 50riveted, welded or otherwise suitably' attached at 5i to the top of theadjacent end of the tube section 5ib has an extension 62 which overhangsthe adjacent end of the tube section 5Ia and is apertured at 53. Inassembly the tube section -5lb is applied endwise to the tube sectionSla which registers the apertures .53 with the apertures 55, and thepivot pin 5l is inserted 'through these registering apertures and headedor otherwise secured in place to hingedly mount the tube section 5Ibv onthe outer end of the tube section 5Ia. The top 55 of the bracket 55serves to cover the opening formedv in the adjacent end of the tubesection Sla by striking the ears 58 up therefrom and the end of thebracket may be closed to complete this closure if desired. lhe extensionor overhang of the pivotal mounting enables the tube sections to bebrought together endwise into abutting relation without interfering withthe swinging movement of the outer tube section 5ib.
